Air Quality Program

Blue SkyThe Air Quality Program actively responds to air quality complaints and issues Open Burning Permits in Weld County to protect public health and the natural environment.

This is facilitated through a contract with the Colorado Department of Public Health and Environment, which provides authority and funding to enforce state air quality regulations.


Responsibilities of the Weld County Health Department's Air Quality Program include:

  • Issuing appropriate Open Burning Permits
  • Investigating complaints about odor and smoke that affect air quality
  • Maintaining scientific instruments that monitor ozone, carbon monoxide, and particulates less than 10 microns in diameter and less than 2.5 microns in diameter
  • Inspecting facilities that are registered and using chlorinated fluorocarbon refrigerants
